Patent DE-3135048-A1 (DE)
Title: Control system for the level of the molten metal in continuous casting moulds
Inventor: BARAN DETLEF
IPC: B22D11/18
Filed: 1981-09-04
Abstract: In the abovementioned control system, a PD controller (24) is used as the correcting variable generator for the servovalve (14), the hydraulic correcting variable of which is continuously applied to the hydraulic feed lines to correct the displacement travel of the actuating cylinder (11). As a result, the operating point of the PD controller (24) cannot drift. The servovalve (14) has a nonlinear, shallow throughflow characteristic in the operating range, making it possible to convert very small electrical signals directly into hydraulic actuating signals and thus to displace the plug in accordance with the controller output. By inserting a bypass valve (19) into the hydraulic feed lines (13, 13a) of the actuating cylinder (11), the said cylinder can be switched to manual operation. In this arrangement, the servovalve (14) controls the actuating cylinder (11) in accordance with a predetermined throughflow characteristic with a gently rising central portion (I) in the region of the origin and steep flanks (II) at the sides. The servovalve (14) and the bypass valve (19) are rigidly connected as a constructional unit to the actuating cylinder (11). The actuating cylinder (11) is designed as a differential cylinder. <IMAGE>

Patent DE-3140470-A1 (DE)
Title: Device for transporting liquids
Inventor: KUHN ERNST DIPL ING
IPC: F17C13/08
Filed: 1981-10-12
Abstract: The invention relates to a device for transporting liquids, in particular liquefied gas, having a closed container. If different liquids are transported in one container having two or more chambers which are separated from one another by partitions, exchange of liquid between the chambers is generally to be avoided. This applies to liquids having different chemical or physical properties, but also to those liquids which may not be different in the latter sense, but have to be separated from one another, for example for tax reasons. Especially when transporting liquefied gas, depending on the boundary conditions, quite different pressures can occur which would always have to be absorbed by a correspondingly thick and rigid partition. According to the invention, it is now proposed that the chambers, separated by means of a partition, be connected to one another via a connection line constructed as a pipe, the pipe ends each being arranged in the region of the upper container wall. Furthermore, the pipe is constructed and/or arranged in such a way, and/or means are assigned to the pipe in such a way that exchange of liquid between the chambers is prevented by means of a gas bubble. Pressure compensation is thus achieved by simple means with simultaneous sealing-off in respect of exchange of liquid, with the result that the partition can also be of relatively thin and thus light construction. <IMAGE>
Patent DE-3142382-A1 (DE)
Title: Manufacturing principle for multi-hull ships and boats
Inventor: PFEIFFER JOHANNES
IPC: B63B1/14
Filed: 1981-10-26
Abstract: Larger multi-hull boats have two main disadvantages: distress position after a capsize (the stable upturned position permits no righting without external assistance); large space required for berthing. Both main disadvantages are removed at the same time by all floats and/or hulls being combined by known devices to form a common buoyancy body which can be operated as a single-hull-like vessel in the normal position and rights itself again automatically in the upturned position by means of sufficient instability caused by the interaction of shaping and weight arrangement. In order to create optimum preconditions for this, the combined floats and/or hulls form according to the invention an approximately cylindrical buoyancy body (shown hatched in the drawing). The invention can be applied to all types and sizes of multi-hull ships and makes their fundamental technical superiority (lighter, faster, more space etc.) over single-hull ships complete. <IMAGE>

Patent DE-3148481-A1 (DE)
Title: Time-controlled window closer
Inventor: STEMKE LOTHAR
IPC: E05F1/00
Filed: 1981-12-08
Abstract: Window-closing device controlled as a function of time, having a pull cord (3) which can be wound on a drum (1) and which can be partially unwound from this. The drum (1) is equipped with a restoring spring which is respectively tensioned during the opening of the window. By means of a detent pawl (25) engaging into a toothed rim (10) of the drum (1), the drum (1) is retained in the tensioned position of the restoring spring. The detent pawl (25) is under the influence of a mechanical time switch (32) and, after a ventilation period which can be set as desired has expired, releases the drum (1) or the restoring spring in order to close the window. So that the force accumulator of the time switch is also tensioned during the opening of the window, there is arranged between the toothed rim (10) of the drum (1) and the wind-up gear wheel (41) of the time switch a gear-type connecting member (55), which is in engagement with the toothed rim (10) and which is brought into engagement with the wind-up gear wheel (41) as a result of the unwinding rotation of the drum (1). To guarantee an unimpeded run-off of the time switch, at the end of the unwinding rotation the connecting member (55) is respectively uncoupled from the wind-up gear wheel (41) again. <IMAGE>

Title: Method and recording plate for producing electrophotographic images
Inventor: HEINRICH HANS DIPL PHYS DR
IPC: G03G15/06
Filed: 1981-12-18
Abstract: The invention relates to a method and a recording plate (3) for producing electrophotographic images. The latter are generally obtained by exposing an electrically charged plate (3) and subsequently developing with the aid of an ink pigment (toner). In this process, it is to be prevented that charges flow off at the edges of the photograph and thus that the image becomes impaired. The invention provides for the purpose of improvement in this respect that at least during development the photograph is surrounded by an electrically conductive frame (12) which is kept at least approximately at the potential of the image surface. The recording plate can also be provided permanently with such a frame (12), which is set at the matching potential during the developing operation. Recording plates according to the invention are particularly suitable for use in medical X-ray diagnostics. <IMAGE>

Title: Press, especially for the manufacture of wood glue binders
Inventor: HAAS WOLFGANG
IPC: B27M3/00
Filed: 1982-04-27
Abstract: Presses for the manufacture of wood glue binders have a plurality of pressing chambers, along the length of which are arranged a plurality of pressing assemblies which are provided with a pressing ram and are usually hydraulic. Each chamber is designed so as only to press one wood glue binder as it is not possible to press a plurality of wood glue binders situated next to one another with one pressing assembly, as the binders are of different heights. The press according to the invention is characterised by a pressure and level equalising element which can be attached to each pressing assembly and consists of a closed casing, a plurality of piston rods being guided through the casing wall facing the wood glue binders to be pressed, which piston rods can be jointly acted upon by a volume of hydraulic fluid connected to the casing. An even distribution of pressure ensures that the same force is transmitted to each piston, so that a plurality of wood glue binders of different heights situated next to one another are nonetheless pressed with the same degree of force. <IMAGE>
